Objective To study the effect of ultrasound guided curettage after methotrexate and mifepristone in the treatment of endogenous caesarean scar pregnancy.Methods A retrospective analysis was performed on 43 patients of endogenous caesarean scar pregnancy undergoing treatment of ultrasound guided curettage after methotrexate and mifepristone.Results 39 cases were successful,4 cases were transformed to laparotomy because of intraoperative blood loss,7 cases of bleeding after curettage were successful by uterine carity placed double lumina Foley catheter. Conclusion Ultrasound guided curettage after methotrexate and mifepristone is a safe,effective,little trauma and low cost method in the treatment of endogenous caesarean scar pregnancy,it especially adapts to primary hospital.

The factor of antiapoptosis in cancer is recently identified as survivin. Survivin is prominently overexpressed in embryonic and fetal tissues, and various human cancers. It is potentially involved in both inhibition of apoptosis and control of cell division. Recently, survivin is found to be correlated with the genesis, progress, and prognosis of urological cancer. Manipulation of the antiapoptotic pathway maintained by survivin may be beneficial for cancer therapy. Progressive research of survivin in urological cancer.

Objective To investigate the regulative effect of interferon gamma (INF?) on the expression of platelet-derived endothelial cell growth factor / thymidine phosphorylase (PD-ECGF/TP) and its relation with the anti-cancer effect of 5′-deoxy-5-fluorouridine (5'DFUR) and 5-fluorouracil (5FU) in T24 bladder cancer cells. Methods PD-ECGF/TP mRNA and protein expressions were determined by RT-PCR and Western blot,respectively.Cytotoxicity of 5′DFUR,5FU or mitomycin C (MMC) against T24 cells was evaluated by MTS assay. Results The expressions of PD-ECGF/TP mRNA and protein were concomitantly elevated in T24 cells after INF? treatment.And INF? decreased IC 50 s of 5′DFUR [from (16.0? 3.6 )mmol/L to (6.2?0.9)mmol/L,( P

0.05 ).Side effects of group A,17%(2/14),were lower than that of group B or C,53%(8/15)and 47%(7/15),respectively(? 2 test=12.21, P

Objective To study the effect of immature dendritic cells (imDC) transfusion in combination with bone marrow transplantation (BMT) on rat kidney allograft survival and its possible mechanism. Methods Renal allograft from DA rat was transplanted to Lewis rat. Forty recipient rats were randomized into 5 groups: (1) Negative control group; (2) imDC group: Lewis rats accepted imDC transfusion in the amount of 2? 107 only; (3) BMT group: Lewis rats accepted bone marrow transplantation in the amount of 2?108 only; (4) imDC + BMT group: Lewis rats accepted both imDC and BMC; (5)Third party donor group: Lewis rats accepted renal allograft from Wistar rats. One-way MLR was performed to assay splenic cell proliferation to allogeneic T cells. Exogenous IL-2 was added at the outset of another group as the former one-way MLR. Normal Lewis rat accepted splenic cells from tolerant rat in the amount of 1?108. DTH was assayed in the trans-tolerance model. Cells from spleen and thymus were harvested from recipient rats for detecting chimerism by flow cytometry. Results The median survival time (MST) of the renal allografts was (7. 12 ? 1. 25) days in negative control group, (24. 36 ? 3. 20)days in imDCs group and (7. 87 ? 2. 10)days in BMT group, respectively. In combined group, the MST was prolonged to (80. 75 ? 16. 88)days, which had significant difference as compared with the former three groups (P

Population genetic data of the STR D13S325 locus in a sample of 216 unrelated individuals of Han population in Wuhan was studied with the method of PCR. 11 alleles and 30 different genotypes were observed.There is no significant deviation from the Hardy Weinberg equilibrium.The DP value was 0 9292,PE 0 6137 and PIC 0 7755.The results of study of 200 meiosis showed no mutation.The results prove that this STR Locus is useful in the forensic sicence practice in Han population in Wuhan.

Objective To search for new tumor markers from urine of bladder transitional cell carcinomas. Methods Urine samples from 61 bladder cancer patients who were histologically diagnosed and 53 healthy volunteers and 42 cases with other urogenital diseases were analyzed using surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) IMAC-Cu-3 ProteinChip technology,which can specifically bind the metal-combining-proteins.Proteomic spectra were generated by mass spectrometry.A blinded test set was used to determine the sensitivity and specificity of the differentially expressed markers. Results Four differentialy expressed potential markers were identified.Their corresponding molecular weights were 3445,3703,3896 and 5932, respectively.The 3445 protein was identified as ?-defensin,with its sensitivity for diagnosing bladder cancer being 80% and specificity being 75%.The sensitivity of 3703 protein was 32%,while its specificity was 94%.97% of the patients who were positive for 3703 protein were with high grade and invasive bladder cancer.The sensitivity for 3896 and 5932 proteins were 78% and 55%;the specificity for them were 40% and 35%,respectively. Conclusions SELDI-TOF-MS ProteinChip technology is a quick,easy and practical,high throughput analytic method.It can screen out several relatively specific,potential markers from urine of bladder cancer patients,so it has better clinical feasibility.

As an excellent unicellular biological model, Tetrahymena pyriformis S1 has been employed in studying the biological effects of the chemical elements. The nutritious and/or toxic effects on T. pyriformis S1 induced by As, Se, Te, Re, Ir have been observed. Trace amounts of As, Se, Re and Ir added in the peptone-glucose culture medium could stimulate the cell proliferation of T. pyriformis in the following range of concentration respectively: As 0.03-0.05 ppm, Se 0.01-1.0 ppm, Re 0.02-0.08 ppm, Ir 1.0-3.0 ppm, whereas Te only showed its inhibitory effect on the growth of cells.

Purpose:To study the diagnosis and treatment of urachal carcinoma, and to improve its prognosis.Methods:Three patients with urachal carcinoma are described. In addition, many related literatures from Medline and Chinese journals are reviewed. Results:All three cases were presented with subumbilical masses, and received urachectomy and partial cystectomy. One of them had Bricker's sugery. Two patients survived for 53 and 25 months without tumor. Conclusions:History and physical examination should be given special emphasis. Early detection and well planned regimen can improve the patients' prognosis.
